<p><strong><span style="font-size:12.0pt; ">Examples:</span></strong></p>
<p>If an applet (created with either <a href="http://www.w3.org/TR/WCAG10-HTML-TECHS/#edef-OBJECT">OBJECT</a> or <a href="http://www.w3.org/TR/WCAG10-HTML-TECHS/#edef-APPLET">APPLET</a>) requires  user interaction (e.g., the ability to manipulate a physics experiment) that  cannot be duplicated in an alternative format, make the applet directly  accessible.</p>
<p>  If an applet creates motion, developers should provide a mechanism for  freezing this motion (for an example, refer to <a href="http://www.w3.org/TR/WCAG10-HTML-TECHS/#ref-TRACE" title="Link to reference TRACE">[TRACE]</a>). Also, please refer to the  next section for information about making audio and video presentations  accessible.</p>
<p>  For more information about developing accessible applets, please refer to <a href="http://www.w3.org/TR/WCAG10-HTML-TECHS/#ref-JAVAACCESS" title="Link to reference JAVAACCESS">[JAVAACCESS]</a> and <a href="http://www.w3.org/TR/WCAG10-HTML-TECHS/#ref-IBMJAVA" title="Link to reference IBMJAVA">[IBMJAVA]</a>. These companies have  been developing an Accessibility API as well as making the Java Swing classes  accessible.</p>
